I am sorry this is happening to you. It sounds to me that you do have a case, but usually this is decided in court by what is known as a battle of the experts. Also, you will need to file suit fairly quickly so that the statute of limitations does not expire. Let me explain further.
In a medical malpractice case, the plaintiff must normally prove that (1) the defendant/doctor owed him a duty to act according to an applicable standard of care, (2) the defendant breached the applicable standard of care, (3) he suffered an injury, and (4) within a reasonably medical probability, the defendant’s breach proximately caused his injury.
To prove this, you will need to hire a medical malpractice attorney who in-turn will hire a oral surgeon as an expert to testify that what your oral surgeon did fell below the acceptable standard of care and that as a result you suffered the injuries you complain of.
If you have a viable case [one where the cost benefit weighs in your favor in addition to the good facts such as your], then a local malpractice lawyer should be willing to take the case on a 33% contingency fee basis if the case settles or up to a 45% contingency fee basis if the case goes to trial.
Normally you would want to make an appointment to see the lawyer after you get your 5 years of relevant medical history; but since you are having some problems in that area, I would say just go with the medical papers that you have obtained thus far and let the lawyer subpoena the rest for you in the context of litigation discovery.
If you tell me what city and state you are located in, I can try to help you find a list of lawyers to choose from.
